Lawmakers in California have voted that a law to reduce carbon emissions be extended till 2030. This happened a few weeks after Donald Trump, President of the US, said that his government would pull out from the Paris climate accord. As per the policy, firms will have to buy permits in order to release pollutants in the air. Jerry Brown, Governor of California, stated this decision – taken both by Republicans and Democrats – to be a brave one. The state is looking to reduce emissions of greenhouse gases by 40% from the levels of 1990 by 2030.
